Mac computers: Liquid damage is not covered by warranty
Damage due to liquid exposure is not covered by the Apple One (1) Year Limited Warranty or the AppleCare Protection Plan (APP).
Liquid Contact Indicators (LCI) have been added to specific locations on current Mac notebook and desktop computers and wired or wireless keyboards to help determine if systems have been exposed to liquid.
Benefits under the manufacturer's warranty are in addition to rights provided by consumer law. For details see this page.
